do you think china will have the most advance technology in the world?
No. Technology is based on Science. Science is based on sharing, collaboration, and on reusing everything existing that’s best fit for a thing. The world is more and more globalizing: so it is hard to imagine the technology of a country going better than the one of another. The only thing we can imagine is difference of richness (less and less true between whole countries) and difference between fields / way-of-doing-things.
You cannot do good technology alone. Nowadays you need factories around the whole globe to make a single car.
